The ongoing policy debate about pharmaceutical and biologic patents has been coopted by those who don’t like patents—including those who have a financial incentive not to like patents. These paid mercenaries concoct and then disseminate fraudulent “reports”, which have become the lifeblood for patent critics. Even when the inaccuracies and lies are clearly identified, the cacophony of patent haters drowns out the truth thanks to a complicit, ideologically aligned popular press that continues to cite and rely on fabricated “findings” that couldn’t stand up to the scrutiny of your average fifth grader.

The U.S. Court of Appeals for the Seventh Circuit agreed with a district court earlier this week that neither a settlement agreement between AbbVie and a number of generic biologics companies, nor the 132 patents owned by Abbvie covering its blockbuster drug, Humira, violate the Sherman Antitrust Act. This holding, which is significant in its own right, also has broader implications for patent-antitrust analysis.

Innovator (or “reference”) biologic drug makers and small-molecule drug makers face differing legal obligations with respect to public patent disclosures. Under the Hatch-Waxman Act, reference small-molecule drug makers are required to provide to the U.S. Food and Drug Administration (FDA) a list of the patents covering the active ingredients, compositions, formulations, and methods of treatment for their approved reference drug products, which the FDA in turn is required to publish in its “Orange Book.”  21 U.S.C. § 355(b)(1), (c)(2). The publication of such patents in the FDA Orange Book thus gives all generic drug applicants advance notice of the patents to be asserted by a reference drug maker in future Hatch-Waxman litigation.

The U.S. House of Representatives yesterday approved two bills meant to lower prescription drug prices and sent them on to President Joe Biden for approval. The Advancing Education on Biosimilars Act and the Ensuring Innovation Act were introduced by U.S. Senator Bill Cassidy, M.D. (R-LA) and broadly aim to improve the current market for cheaper generic drugs.

On July 1, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed a holding of the U.S. District Court for the District of New Jersey in Immunex Corporation, Amgen Manufacturing, Limited, Hoffman-La Roche Inc. v. Sandoz, Inc., Sandoz International GMBH, Sandoz GMBH, holding that Sandoz failed to prove that the asserted claims were invalid for obviousness-type double patenting (ODP), failure to meet the written description requirement, and obviousness for lack of motivation to combine the prior art references. The ruling for now blocks Sandoz from marketing its biosimilar version (Erelzi) of the popular rheumatoid arthritis drug, Enbrel. Judge Reyna dissented, arguing that certain clauses of the licensing agreement were illusory, thereby rendering the agreement an effective assignment for purposes of ODP.

The United States Senate Finance Committee today considered the U.S.-Mexico-Canada Agreement (USMCA) in an Open Executive Session and voted 25 to 3 to move the bill forward.

The USMCA enjoys wide bipartisan support, but Senators Pat Toomey (R-PA), Bill Cassidy (R-LA) and Sheldon Whitehouse (D-RI) voted against the bill. Toomey and Cassidy objected largely to process issues, as the Committee was not allowed to present amendments under a fast-track process, while Whitehouse was critical of the agreement’s lack of urgency on climate change. President Donald Trump and House Speaker Nancy Pelosi reached agreement on the USMCA, which would, if ratified, replace the North American Free Trade Agreement (NAFTA), on December 10. Notably for the IP community, the new version struck down provisions that would have expanded regulatory data protection for biologics inventions from five years in Mexico and eight years in Canada to 10 years in both countries.

Yesterday, in an opinion authored by Judge Moore, the Court of Appeals for the Federal Circuit (CAFC) affirmed the District of Delaware’s decision that: 1) U.S. Patent No. 5,856,298 (the ‘298 patent) belonging to Amgen was infringed by Hospira and not invalid; 2) 14 batches of drug substance for Hospira’s erythropoietin biosimilar drug product were not covered by the Safe Harbor provision of 35 USC § 271(e)(1); and 3) Amgen had proven that it was entitled to a jury verdict of $70 million in damages. Additionally, the CAFC affirmed the jury’s verdict of noninfringement of U.S. Patent No. 5,756,349 (the ‘349 patent).

Earlier this week, Speaker of the House of Representatives Nancy Pelosi (D-CA) reached an agreement with President Donald Trump on passage of the United States-Mexico-Canada Agreement (USMCA), which if passed into law would replace the defunct and much maligned North American Free Trade Agreement (NAFTA). Not everyone is happy about the latest version of the USMCA agreed upon by the White House and House Democrats, including the U.S. Chamber of Commerce, which continues to support the overall agreement but has great concerns about the new provisions in the latest negotiated agreement between President Trump and Speaker Pelosi, which strikes expanded protection for biologic drugs from the agreement completely. Over the summer, House Democrats vocally opposed granting 10 years of regulatory data protection (RDP) for biologics inventions—an increase from 8 years in Canada and from 5 years in Mexico—arguing it would result in higher drug prices and delayed entry for biosimilars.

On September 13, U.S. Trade Representative Robert Lighthizer reportedly expressed a willingness to negotiate on several points of contention regarding the U.S.-Mexico-Canada Agreement (USMCA), including potentially reducing the 10-year period of intellectual property protection for biologic medicines. In response to this, the Pass USMCA Coalition is touting a memo penned by Former Department of Health and Human Services (HHS) Secretary Tommy Thompson aimed at “debunking the widespread myth that the USMCA will drive up drug prices.” Thompson, also a four-term governor of Wisconsin, now advises the Pass USMCA Coalition. Thompson’s memo focuses on three key arguments that he considers myths

In the face of pressure to pull provisions in the United States-Mexico-Canada Agreement (USMCA) that would grant 10 years of regulatory data protection (RDP) for biologics inventions, a recent report claims that the requirement would not result in higher drug prices for U.S. patients. The USMCA is currently being negotiated, but the chances of a vote this summer are quickly dwindling. In addition to other objections, many Democrats have opposed granting 10 years of RDP—an increase from 8 years in Canada and from 0 in Mexico (the U.S. period of exclusivity is longer, at 12)—arguing it would result in higher drug prices and delayed entry for biosimilars. Patrick Kilbride, Vice President of International Intellectual Property for the Global Intellectual Property Center (GIPC) at the U.S. Chamber of Commerce, has argued here before that the data does not support those claims.

In our last article exploring patent trends across 12 industries, we addressed the industrial design industry. Today’s article pertains to the therapeutic and diagnostic molecules industry. Few other industries have the potential to so dramatically affect individuals’ lives as does this industry. While on a day-to-day basis it can be easy to forget the intensive bench work and clinical trials that are being undertaken in attempts to better treat or cure disease, it is this steady pulse of investment and effort that has led to the cure of many ailments and diseases. Rather recently, biologics advancements have expanded the field to no longer merely rely on small-molecule compositions but to draw upon a large pool of sophisticated large-molecule options. However, research and development in the pharmaceutical space remains heavily regulated and extraordinarily expensive. Thus, investments must be chosen and protected wisely.

Promoting public health has always been a bipartisan priority in Washington, D.C. Under the previous administration, lawmakers passed the 21st Century Cures Act and launched the cancer moonshot, two initiatives that aimed to transform health outcomes through greater investment in the next generation of medical treatments. In his State of the Union address last month, President Trump announced an ambitious plan to end HIV/AIDS by 2030 and increase funding for often-neglected childhood cancers. For each of these initiatives to be successful, lawmakers must recognize that investing in the cures of tomorrow requires continued bipartisan cooperation. This rings true for passing the U.S.-Mexico-Canada Agreement (USMCA), as well. The next generation of medical innovation depends on significant private sector investments. The intellectual property (IP) provisions of USMCA help to lay the foundation for continued investment into the research and development (R&D) of innovative cures across North America. In particular, the 10-year term of regulatory data protection for biologics will help ensure that North America continues to lead the world in developing life-saving technologies.

While part one of this two-part series on intellectual property (IP) due diligence focused on a life science company’s own IP portfolio, part two will address a company’s understanding of how it fits into the market by considering its freedom to operate, as well as its competitors’, and the interplay of patent and regulatory exclusivity as it relates to the company’s product. Patent and regulatory exclusivity—two areas that can provide the most value and protection to a life science product—are very interrelated. Simply identifying when a key patent naturally expires is not sufficient, because regulatory exclusivity could possibly extend the company’s ability to keep competitors off the market or allow competitors to speed up entry in certain situations.

Patents covering an antibody are often claimed by the antibody’s function (the residues where it binds to the antigen) rather than its structure (amino-acid sequence). This tactic can successfully cast a very wide net of patent protection over potentially millions of different antibodies. In doing so, even if the patent holder’s own antibodies never make it out of the laboratory, the patents can nevertheless corner the market on intellectual property covering a new class of inhibitors. The risk of this strategy, however, is that extremely broad patent scope can simultaneously doom a patent’s validity for not being sufficiently enabled or lacking written description. As an example, a recent decision from the District of Delaware, MorphoSys AG v. Janssen Biotech, Inc., No. 16-221 (LPS) (Dkt. 471) (Jan. 25, 2019), invalidated broad antibody patents for not being sufficiently enabled, as well as coming near to invalidating the same patents for lacking written description. The case is important to the growing body of patents covering biologic drugs because it delineates more precisely when functionally-claimed antibody patents can survive enablement and written description challenges.
